I purchased two heltec Esp32 sx1276 ct62 shells from heltec. Using ftdi i can program Esp32 Wroom 32 using the Esp32 Dev Board on Arduino. But no luck with ct62. Do i have to use a different arduino board?
Ftdi ct62.
Rx. TXD
Tx. RXD
Gnd. Gnd
En->flash switch -> 10kohm-> 3.3v
0 -> reset switch -> 10kohm-> 3.3v
2 -> Gnd
VCC -> 3.3v
I followed the arrangements as here:
ESP32-wroom-32, esp32-S: flash, pinout, specs and IDE configuration – 1
ESP32, continue the little guide on how to use this low cost but powerful microcontroller with WIFI integrated. Pinout, specification and IDE configuration to start use your esp32-wroom-32 esp32-s variant.
I get the error on arduino as “fatal error could not find the Esp32 dev board.”
I changed the board in Arduino to Heltec Wifi Lora 32 but again no luck as i get the error:
esptool.py v3.3
Serial port COM3
Connecting......................................
A fatal error occurred: Failed to connect to ESP32: No serial data received.

does not exist or your board is not connected
So no luck with ct62. Do i have to use a different arduino board? Or it has to do with connections? Please help
